Officials said they were told a male underclassman told another student that he was going to shoot up the school.

The threat about shooting up the school was not specific and the student reported it to the school's dean, according to authorities.

Investigators said they looked into the threat, including interviewing students and the teen who made the threat and found it to not be credible.

Officers said the incident took on a life of its own via social media and that student began posting about it on Facebook, which began the rumor mill and scared many people.

Authorities said principal Robert Lundquist addressed the incident on the morning announcements and felt he needed to set the record straight.

"My principal handled the situation very well. (He) went on the intercom and they were handling it," said student Nakeia Robinson.

Lundquist said in a statement, "Last week there was an off-campus threat by one of our students who said he was going to shoot up the school. This lead to an investigation by the school and the police department. The findings were no facts substantiating the rumor."

Parents said they are not happy that the principal handled the situation in such a manner, and many said they wanted a reverse call notification.

One parent said she didn't know about the situation until her child sent text messages with photos of police outside of the school.

After the investigation, it was also uncovered that the student made a similar comment last month.

The student has since withdrawn from the school, according to investigators. He was not arrested.

Students at the high school will practice a Code Red drill Thursday. It is the highest level of alert and was planned months ago.
